Description

Technical Field

[0001] The utility model relates to the technical field of polycarboxylic acid water reducers, in particular to a storage and homogenization device for polycarboxylic acid water reducers. Background Art

[0002] Polycarboxylate water reducer is a high-performance water reducer and a cement dispersant used in cement concrete.

[0003] It is widely used in projects such as roads, bridges, dams, tunnels, high-rise buildings, etc. This product is green and environmentally friendly, non-flammable, non-explosive, and can be safely transported by train and car.

[0004] Polycarboxylic acid-based high-efficiency water-reducing agent products can be divided into two categories according to their main chain structures: one category is based on acrylic acid or methacrylic acid as the main chain, with polyethers of different side chain lengths grafted on them.

[0005] The other type is polyether with maleic anhydride as the main chain and different side chain lengths. Based on this, a series of high-performance water-reducing agent products with different characteristics have been derived.

[0006] Before the emergence of polycarboxylic acid admixtures, there were lignin sulfonate admixtures, naphthalene sulfonate formaldehyde condensates, melamine formaldehyde condensates, acetone sulfonate formaldehyde condensates, amino sulfonate formaldehyde condensates, etc.

[0007] In the early 1980s, Japan took the lead in successfully developing polycarboxylic acid-based water reducers. The new generation of polycarboxylic acid-based high-efficiency water reducers overcomes some of the drawbacks of traditional water reducers and has outstanding advantages such as low dosage, good collapse resistance, low concrete shrinkage, strong adjustability in molecular structure, great potential for high performance, and no use of formaldehyde in the production process.

[0008] At present, when polycarboxylate water reducer is stored for a long time, in order to avoid water-material stratification due to continuous storage of polycarboxylate water reducer, it is necessary to shake the storage tank regularly to prevent the stratification time from being too long, so that when it is taken out for use later, it cannot be quickly mixed and put into use. Utility Model Content

[0009] The utility model aims to solve the above-mentioned shortcomings in the prior art, and proposes that when the polycarboxylate water reducer is stored in a tank for a long time, the tank can be connected together for shaking treatment to avoid the long-term stratification of the stored polycarboxylate water reducer.

[0010] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0011] A storage and homogenization device for polycarboxylic acid water-reducing agent is designed, comprising a base, wherein the upper end surface and the lower end surface of the base are respectively provided with a storage groove and a built-in groove, and a shaft sleeve is provided at the connection position of the storage groove and the built-in groove, the surface of the shaft sleeve passes through the interior of the base, and the connection position of the shaft sleeve and the base is fixed by welding, a motor is fixed on the inner wall surface of the built-in groove by a bracket, a rotating shaft for driving is provided inside the motor, and the other end of the rotating shaft extends outward and is rotatably sleeved with the shaft sleeve, a rotating table is provided inside the storage groove, and The other end of the rotating shaft passes through the shaft sleeve and is assembled with screws at the center of the rotating table.

[0013] In detail, a plurality of legs are fixedly mounted on the lower end surface of the base, and universal wheels are fixedly mounted on the lower ends of the legs. The number of the legs is at least three and they are evenly distributed.

[0014] In detail, the outer wall surface of the base is provided with symmetrically distributed cylinders, the outer wall of the base is provided with grooves for inserting and assembling the cylinders, the interior of the cylinders is provided with a piston rod for extension and contraction, and the piston rod and the cylinders are interpenetratingly provided.

[0018] 1. The tank body is placed in the storage groove of the base, and the square base below it is inserted into the square groove, which can be limited and positioned. The piston rod of the cylinder body is retracted, so that the limit frame enters the annular groove. The limit wheels at different positions contact the inner wall of the annular groove to form a resistance effect, so that the up, down, left and right positions of the tank body can be stably limited when rotating.

[0019] 2. The motor's shaft rotates to drive the rotating table to work in conjunction. The rotating table can drive the rotation of the tank body through the limiting insertion effect of the square bottom table and the square groove, so that the polycarboxylate water-reducing agent stored in the tank body can be shaken evenly. The sphere on the lower end face of the rotating table is set to make it roll in contact with the inner bottom end of the storage groove, which can reduce the loss of the shaft and reduce the friction resistance, thereby improving the rotation stability of the tank body.
